GAS-HEATER.

SPECIFICATION forming part of Letters Patent No. 744,898, dated November 2 1, 1903..

Application filed January 19,1903. Serial No. 139.536. (No model.)

To all whom, it may concern:-

Be it known that I, JAMES H. BROWNLEE, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Gas-Heaters, of which the following is a specification.

My invention relates to a new and useful improvement in gas-heaters, and relates to that class of heaters adapted to be placed over an ordinary illuminating-gas jet for the purpose of cooling and radiating the heat; and this invention has for its object to provide a simple, cheap, but effective and durable device of this character and to provide an improved holder for securing upon the gas-jet, so that, if desired, light and heat can be had at one time from the same jet.

With these ends in view this invention consists in the details of construction and 00111- bination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which-.

Figure 1 is a vertical sectional view through my improved heater, showing the same attached to a gas-jet; Fig. 2, a plan view of the heater; Fig. 3, a perspective view of the holder or bracket which supports the heater; Fig. 4, a perspective view of aholder formed of wire; Fig.5, a vertical sectional view of the socket adapted to be formed with the vertical, and this ring is adapted to fit within the hood A, leaving a space in between the hood and thering, as shown in Fig. 1. The ring 13 is lined with asbestos or other fireproof material, as shown at O, and this fireproof material is held in its place by turning over the top and bottom edges of the ring upon the material, thus clamping it in place. The inner face of the top of the hood A is also protected by fireproof material, such as asbestos, as indicated at 1). These two portions of the heater are held in their relative position with one another by means of the holder F. The vertical portions F of the holder are adapted to come in contact with the outside of the ring B upon opposite sides, and the ring is secured to the holder by means of the screw-bolts G. The ends F of the holder come in contact with the inside of the hood A upon opposite sides, and this hood is secured to the holder by means of the screwbolts H.

The form of holder shown in Figs. 1 and 3 is a holder designed to be cast, and that form shown in Fig. 4 is a holder bent up out of wire.

In Figs. 1 and 3 the holder is provided with a socket 1, adapted to fit over the gas-jet, and in the form of holder shown in Fig. at the socket is formed separate, as shown at J in Fig. 5, said socket being provided with an annular groove J near its lower end, around which the wire is twisted, so as to hold the same in place.

It may be at times advisable to adjust the relative positions of the hood and ring or raise or lower the heater relative to the gas-jet. For this purpose a series of holes G may be provided in the vertical portion F of the holder, through which the screw-bolts G pass, and a series of holes H may be provided in the ends F of the holder for the adjustment of the hood by changing the screw-bolt H from one hole to the other. In the form of holder shown in Fig. 3 the screw-bolts Gpass through the loops K, and the screw-bolts H pass through the loops L, formed in the ends of the wire holder, and as these loops are elongated the adjustment can be effected by loosening the screwbolts and sliding the holder to any position desired and then tightening the bolts again.

It may be desired at times to utilize the heater for heating liquid or articles of food by setting the same upon the top of the heater, and to prevent the cooking utensils from falling off of the heater by a slight jarI form on the top of the heater a wire guard L being In testimony whereof I have hereunto set a parabolic cylindrical surface, spark-balls my hand in presence of two subscribing Witfor electric disruptive discharge, said balls being arranged in the center line of the paranesses.
